WILLIAM H P or raga baa,

V SANITARYWELLJFOP Appli cation 'filed November 9, Q

The object of my invention is to provide a sanitary well top of simple,durable and inexpensive construction, and which may be formed completeof two pieces of cast'metal, and readily and easily assembled and'fittedV to a well top and pump with a minimum of labor, and when so fitted itwill provide a water and dust tight well top.

My invention consists in the construction,

arrangement and combination of the various" parts of the device, wherebythe objects contemplated are attained, as hereinafter more fully setforth, pointed out in my claim, and

illustrated in the accompanying drawing, in which:

Figure 1 shows a side elevation of my improved well top with a pumpfitted thereto.

Figure 2 shows a top or plan view on an enlarged scale showing myimproved well top, a portion being broken away to show structuraldetails.

Figure 3shows an edge elevation of same illustrating the water and dusttight locking connection between the two sections.

Figure 4: shows a detail sectional view on the line 4- 1 of Figure 2,thepositionof the bolt and the pump base being indicated by dottedlines. y Figure 5 shows a sectionalview onthe line 5-5 of Figure 2; and

Figure 6 shows a sectional view on the line 6-6 of Figure 2. p

Referring to the accompanying drawing, have-used the reference numeral10' to indi cate generally a pump of ordinary construction,the shape ofa portion of its base being indicated by dotted lines in Figure'et.

My improved well top is preferably formed of cast metal complete in twoparts.

Each part has at its central portion a raised fiat pump supporting baseindicated generally by the numeral .11, and preferably semitwo sectionsfirmly togethe1 *a ainst lateral ed therein.

.Then if necessary bolts may be inserted edge} adjacent to the othersection with 'an upwardly, extending rib 15,""extended from the flatpump -base portioni ll downwardly and outward tiOIi- 1"." The oppositesection is'providedatits edge adjacent tothe first section with aninverted U-shapedrib 16 to overlap the' rib 15 as y-to theouter'edgeofthe -sec-g H Q 7 155 clearly'shown in Figure 3, and to lock the 9movement-and at-the same time-provide a water and dust tight joint. i

7 At the raised fiat pump overlapping flanges 17-, shown in Figure 6.v

I g base supporting portion 11, the ad aQent edges of the sections; areprovided with To provide'for bolting apump to improved'well top I haveformed in the portion 11 a series of grooves 18 to receive bolt heads,and these grooves have slots 19 extending upwardly through the well top.On

the downwardly and outwardly inclined portions 12-these grooves 18extend outwardly with their bottoms substantially horizontal, i

so that any water that fiowsinto the groove will discharge outwardlyupon the inclined portion 12, and these outer ends are widened so thatthebolt head may readily be insert:

I On the under surface improved well top, I preferably provide a number;of reinforcing ribs 20, andthey preferably extend' radially as shown inFigure 4.

In practical use with my improvedv well; 7 top. it is'obvious thattheentire device may be formed complete of two sections of cast metal,and they do not needany grinding 15 in position,*and then the sectioncontaining the-inverted U-shaped groove 16 in p0 sitiorrwith the rib 15in the groove 16.

through the openings "13 to hold the well top the pump is placed in"positionfand bolts, are

'plac'ed with their. heads in the grooves 18,.

and are extended upwardly therefrom.

Then the pump is placed in position with the bolts extending through thepump flange and the nuts are then tightened on top and the device isfirmly and securely held in position against movement in all directions.

Obviously, the well top is Completely sanitary because water and dirtcannot enter, and obviously any water or dirt that might enter under thepump base would be prevented from entering the well on account of theraised rib 11a. 7 1

I claim as my invention:

A sanitary well top formed-complete in two sections, each section beingformed with a raised pump seat portion at the center of its inner-edge,theremainder of eachsection having its top surface inclined downwardlyand outwardly, an upwardly extended rib formed on the inner edge of oneof the sections and extending from the raised central portion to theouter end, theother seotion being formed on its inner edge with aninverted U-shaped rib-shaped to receive said upwardly extended rib, andto thereby form a leak proof joint and at the same time seourely lockthe two sections together against movement away from each other. 7
